LYB101 630A High-Voltage Vacuum Circuit Breaker Contact Arm – Silver Plated Copper Contact Sleeve for Switchgear

The LYB101 is a high-performance 630A circuit breaker contact engineered for reliable power transmission in high-voltage switchgear systems. This contact arm (also known as a contact sleeve) is manufactured from high-purity copper with a precision-polished, silver-plated finish to ensure minimal resistance and maximum conductivity. Designed for use in vacuum circuit breakers (VCB), the LYB101 features a smooth, tapered entry profile to facilitate seamless engagement with tulip contacts while reducing mechanical wear during switching operations. Its robust construction provides exceptional thermal stability and long-term durability in demanding industrial and utility distribution environments.
